In this paper we consider spaces of unequally smooth local bivariate quadratic splines, defined on criss-cross triangulations of a rectangular domain. For such spaces we present some results on the dimension and on a local basis. Finally an application to B-spline surface generation is provided.

Abstract
In this paper we consider spaces of unequally smooth local bivariate quadratic splines, defined on criss-cross triangulations of a rectangular domain. For such spaces we present some results on the dimension and on a local basis. Finally an application to B-spline surface generation is provided.
